Cu8(SO4)4(CO3)(OH)6 · 48H2O
May contain minor Mg, Ni.
Translucent blue
Named for the type locality.
The originally reported sulphate content appears to be questionable according to several literature sources; the crystal structure is unknown. Palenzona & Martinelli (2007) suggest a formula (Mg,Cu)x(CO3)y(OH)z•nH2O (x, y, z unknown).

Classification of Nakauriite


7 : SULFATES (selenates, tellurates, chromates, molybdates, wolframates)
D : Sulfates (selenates, etc.) with additional anions, with H2O
G : With large and medium-sized cations; with NO3, CO3, B(OH)4, SiO4 or IO3

4 : Hydrated Compound Sulfates containing Hydroxyl or Halogen

12 : Carbonates with other anions
2 : Carbonates with sulphate
